I am thinking about switching my EMG-81 Active in the bridge to a Tesla AH-3. I have heard demos, but never in real life. Anyone tried these pick ups out before? I play heavy metal (name might give that away) and have been really happy with the EMGs, but feel like trying something new.

If you have tried them out, are they worth the swap? Or are they just good enough to put in if you do not want to spend $100 on the EMGs?
I am also interested in a Tesla pickup and came here looking for experiences. I'm interested in a different pickup though - the plasma x1.
